HYPODERMIC-NEEDLE STERILIZER.

Specification of Letters Patent.

Application led August 17, 1917. Serial No. 186,767.

To all whom it may concern.'

Be it known that we, PORT Rico MARSHALL and HARRY L. Goss, citizens of the United States, residing at Horton, in the county lof Brown, State of Kansas, have invented a new and useful Hypodermic-Needle Sterilizer., of which the following isa specication. f

The subject of this invention is a sterilizer for hypodermic needles, or like articles, and the objects of the invention are, first, to provide a sterilizer which may be easily carried about by a physician, second, to provide a invention hereindisclosed can be made withl sterilizer which is quick 1n its action, third, to provide means for removingthe needles from the sterilizer, fourth, to provide a sterilizer with a container therefor and a fuel compartment in the container, fifth, to provide a sterilizer with means for burning fuel in tablet form, sixth, to provide means for burning volatile liquid fuel in the sterilizer, seventh, to provide aesimple and eiicient sterilizer.

With the foregoing and other objects in view, which will appearyasfthe description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction lhereinafter described and claimed, it being understood 'that changes in the precise embodiment of the in the scope of what is claimed, without departing from the spirit of the invention.

One practical embodiment of the invention is shown in the accompanying drawings, wherein Figure 1 is a vertical cross section kof a sterilizer constructed in accordance with this invention, the same shown in place in its casing.

Fig. 2 is a perspective view of the'sterilizer tank cover.

Fig. 3 is a perspective view of the needle tray.

Fig. 4 is a perspective view of a modified form of fuel burner.

Fig. 5 is a perspective view of the preferred form of fuel burner.

Fig. 6 is a perspective view of the fuel burner support.

Fig. 7 is a vertical longitudinal section of another form of burner for liquid fuel.

Fig. 8 is a side elevation of the sterilizer removed from its casing.

Referring to the drawings by numerals of reference The sterilizer, when not in use, is Stored in a container 1 of rectangular formation, and provided in its top with an inwardly struck portion 2 defining a longitudinal groove. This groove is closed by a friction cover 3 so as to form a compartment in which the fuel tablets may be stored.

The sterilizer proper consists of a suitable casing 4, here shown rectangular, which is providedin its ends and sides with a plurality of ventilator or draft openings 5, which may be arranged as shown, or in any other suitable way. The casinghas a bottom G secured therein in any convenient and well known-manner, and is provided at one end with an opening adjacent the bottom, for the reception of a drawer or slide 7 constitutinga fuel holder support.

The slide or drawer is formed with an upstanding front 8 from which ,is struck out a tongue 9, .which is angled to form a gripping member through which the drawer may be manipulated. The striking out of the tongue 9 leaves a ventilating slot 10, whiclrmay be supplemented by the openings l1, if desired. Along thelongitudinal edges of the bottom. are Iprovided upstanding fianges 12 from a median point on each of which rises a lug 13 which aids in retaining the fuel holder or burner against transverse misplacement. A tongue 14 is-st'ruck yup from lthe rear end of the bottom of the slide and is bent asshown toform a catch to engage and detachably secure the rear end of the burner in place. y

The material of the top ofthe casing is bent to` form a tank 15 preferably rising above the-top which vextends longitudinally of the casing NVithin this tank, andresting on the bottom thereof is loosely placed -a perforated tray 17 the sides of which may `/be bent, as shown, and which is provided with lugs 18 by which the tray may be lifted from the tank. The tank may be closed b a cover 19 when the container 1 is not use The burner or fuel holder, is a metal plate 21 formed with a depending angled end 22 the edge of which is adapted to take into a groove 11, not shown, formed at the juncture of the front 8 of the slide 7 with the bottom. This secures the front end of the burner in place. The rear end of the plate 21 also depends for a short distance and is turned outwardly at the edge, as seen at 23, to take into the catch 14. A plurality of depressions 24, here shown as two, are

formed in the plate 2l, and the material 0f the plate Within these depressions is split, as

shown, to provide-'proper' ventilation for' combustion. Fuel tablets, not shown, are placed in these depressions and ignited.

Should it become necessary or desirable for any reason-to useI a fuel other than the tablets designed for usefinthis:;sterilizer,` a special burner 25, shown in Fig. 4, is providedl. Thisburner. is similar tothe,y onefj ust describedy except that the depending' edges- 22 and 23. arelonger raising.;` the surface higher from the slide bottom. Instead of the deprossionsQ/l, an elongatedlongitudi-u4 The material around the peripheryv of this.

opening isbent to slope downwardlyv and inwardly, as seen. at.A 27, to coperat'ewvith the. downwardly andinwardlysloping'fiange Q8 of a friction cover 29; The'top129 isiprovided with an upstanding frusto `conical burner 30 in which` Ventilating holes 31 are formed. A Wick.. 32- depends -from s' the burner, in whichfit .is frictionally. held, and a friction cap 33 is. adapted to seat,k on Vthe burner when thersaine isfnot inuse.

In practice thedevice is operated in the following inannerz-The sterilizer. is reinovedifroin its container, .or thetank cover taken olfand th'e needles placedinthe. tank and: resting on the tray. Water suliicientfor the purpose is placed inthe. tank andthe coverreplaced. The slide is. Withdrawn and tvv'o special fuel tabletsftaken from the .comf partinent 2,-01 other container, and placed in the depression 24. These tablets are ignited andthe slide'pushedin place". The Water in the tank will boil in one: ini-nnte` andnwill continueto'fboisl for three minutes. When the-needles are thoroughly sterilized lthe needletray may: be lifted out. Thelholespin the tray'willallow all Water todrain fromv the needles. As the special fueltablets used leave no carbon deposit or ash there is no danger of the steri'li'zerfseilingor sinutting articles in thephysicians case.

WVlien-alcohol'i's to be used as the fuel, the burner is removed from the slide and either the burner shown in Fig. Ll, orl thelarnp shovvn.-.in-,lili-g., E5.I substituted.

The clips 2O formed on the ends of the needle tray serve tohold the needlesfvin place andpermitxa needle to be screwed to the syringe Without handlingthe needle.

Hav/ing; thus described the invention, What is claimed as new and sought by Letters- Patent,y is

L AV sterilizer, comprising a` casing, a slide in the casing, tank on-the casing, vand a perforated `Vneedle tray inthe tank.
